Estimate your one-rep max and explore rep curves

Training 1RM Estimator Q&A

AI Strength Coach: Ask questions about 1RM methods, rep ranges, programming guidance, or how tempo and fatigue shift the curves. For the calculator and chart, use the App tab.

Try asking about:

  • • “Which 1RM formula fits heavy sets best?”
  • • “How does tempo change rep strength?”
  • • “Estimate 1RM from 85 kg × 6 (paused)”
  • • “How many reps at 80% for hypertrophy?”

I can help with:

  • • Choosing a formula by lift and rep range
  • • Translating 1RM into training zones
  • • Understanding fatigue and recovery effects
  • • Progression ideas based on your data
